The Late Show with Stephen Colbert

Stephen Colbert riffed on the shocking, "vicious, and so on-brand" tweets: "I want to say something right now that I did not think was possible anymore: I am shocked by something Donald Trump said."

"I thought by now, after five months of this, that my soul had been calcified into a crouton," he said. But then, the nonsensical tweets about the Morning Joe co-hosts came through.

Colbert drew an unexpected comparison from the tweets: "Someone bleeding badly at your door and you say no? It sounds like your heath care plan," he said. "I mean, turning them away from your hotel during the middle of winter is literally the story of Christmas, only there wasn't a wise man in sight."

Ultimately, Colbert realized the tweets weren't a "new low," exactly, but "the same low."

Late Night with Seth Meyers

During his monologue, Seth Meyers was at a loss for words when discussing the president's tweets during a new segment called "I Can't." He merely shook his head in disbelief and somehow mustered the strength to utter, "I Can't."

The Late Night host had more pointed words for POTUS when delivering his "Closer Look" at Trump's knowledge of health care. Meyers was perplexed by what Trump meant when he wrote, "I said no!"

"Said no to what? Your (expletive) meds?” Meyers inquired of the man he described as an "old-school misogynist."

The comedian added, "His Twitter rants have gone from confusing to ‘Mommy, why is the man on the subway yelling so loud and where are is his underpants?’”

The Tonight Show Starring Jimmy Fallon

Setting up a bit, the talk show host explained that since President Trump's agenda is so full, he set reminders on his phone. One "item" that made the list? "Use Twitter to insult Mika Brzezinski because you don't know how to say her name out loud."
